Customizing the script

All changes to the script
takes place in the code of Step 1, which is documented for the purpose.
First, customize the 7 variables near the top of the script per the
comments. Then, locate the <DIV> tag at the bottom of the code,
which reads:

You now need to change the width and height of the
"placeholder.gif" image above using the preset formula:

placeholder width: 2*book image width+4

placeholder height: book image height+2

Note that if you set the
slideshow to flip vertically, then the width and height settings need to
be interchanged, so placeholder width= book image width+2, and placeholder
height= 2*book imageheight+4.

And that's it. FYI the above
customization steps are repeated within the script for easy reference.
